We were camping in E WA State, and a large group of Russian campers took the sites across the road from us. The first thing that happened was that they put several 1/2 gallon bottles of vodka on the table, and a long string of shot glasses. As the day progressed there was more vodka, and they tried to start a fire without success. I took some newspaper and kindling over to help, and made some new friends, which helped later in the evening when they started really drinking and getting abusive. The CG hosts were intimidated, had rocks thrown at them, and other campers were threatened. The park rangers finally quieted them down, but that only lasted when they were present, they should have done more. We were not threatened because of a bit of firewood. The "campers" were removed from the park in the morning.
